# This script manages app build numbers.
|
|
# It returns the next build number to be used.
|
|
# If ran with --tag it will mark current HEAD with new build number.
|
|
#
|
|
# These numbers are used to mark app artifacts for:
|
|
# * Play Store - versionCode attribute (gradle)
|
|
# * Apple Store - CFBundleVersion attribute (plutil)
|
|
#
|
|
# The numbers need to be incremeneted and are maintained via
|
|
# git tags matching the '^build-[0-9]+$' regex.
|
|
# Builds from an already tagged commit should use the same number.
|
|
